Previously we explained how to choose a ski helmet from the construction, today we'll see how to choose a head ski helmet from the type.
Types of ski helmets:
I. The main distinctions in terms of production processes are:
1. PC one-piece helmet: the material of the shell is PC.
The main production process is as follows：
Screen printing is used to print the pattern onto the PC sheet first; blister molding is to make the flat PC sheet into the shape of a helmet.
Cutting and drilling：
By putting the shell on the foaming machine, the shell and body are fused.
2. ABS helmet: the shell material is ABS.
The main production process is as follows.
Injection-molded caps, sanded.
If a pattern is used, make a water sticker of the pattern, apply it to the surface of the head ski helmet, and spray paint it.
The main body is foamed separately.
Glue the body to the shell with hot-melt glue.
PC one-piece helmets verse ABS helmets:
1) PC one-piece helmets are lighter than ABS helmets: general PC helmets weigh 350-450 grams, and ABS helmets weigh 500-650 grams.
2) CLASS A must be made with the ABS helmet.
3) For CLASS B models, the unit-price of PC helmets is higher than that of ABS helmets.
2. From the scope of protection to distinguish: CLASS A and CLASS B, the European standard CE EN1077 distinguish ski helmets into CLASS A and CLASS B.
CLASS B: the earmuffs are soft, CLASS A: the earmuffs are hard.
Comparing the two: CLASS A has more protection scope than CLASS B and is relatively heavier. CLASS B helmets are mainly used in general skiing, CLASS A helmets are mainly used in racing.
3. From the main use to distinguish: ski helmet, cross-country ski helmet, and freestyle ski helmet.
The speed of alpine skiing is faster, so CLASS A helmet is often used; cross-country skiing mainly uses ordinary CLASS B helmet.
